Pregnancy outcomes of overweight and obese women aged 35 years or older – A registry-based study in Finland

OBJECTIVE To compare pregnancy outcomes of overweight and obese pregnant women aged 35 years or older to women aged less than 35 years old. METHODS A registry-based study covering years 2004-2008 including data on women ≥35 years (N=45,718) compared to those <35 years (N=203,930) and their pre-pregnancy body mass index (BMI) (<25, 25-29 and ≥30). In multivariable modelling, the main outcome measures were preterm delivery (<28 weeks, 28-31weeks and 32-36 weeks), low Apgar scores at 5min, small-for-gestational age (SGA), foetal death, asphyxia, Caesarean section, induction, preeclampsia, blood transfusion, admission to a neonatal intensive care unit (NICU), shoulder dystocia, and large for gestational age (LGA). RESULTS Maternal overweight and obesity along with advanced maternal age (AMA) significantly increased the risks of preterm delivery, preeclampsia, foetal death, LGA and Caesarean as compared to women of average weight aged <35 years. When comparing overweight and obese women aged ≥35 years to normal weight women of the same age, the rates of preeclampsia, preterm delivery <28 weeks, LGA and low Apgar score were significantly increased. When observing overweight and obese women <35 years as a reference group, the risks of preterm delivery and foetal death were significantly increased. CONCLUSIONS The risks were increased by maternal age≥35 years and both obesity and overweight. The combined effect of AMA and either overweight or obesity appeared to be a high risk state particularly for stillbirth and preterm delivery.

The association of episiotomy with obstetric anal sphincter injury--a population based matched cohort study.

Objectives To estimate the independent association of episiotomy with obstetric anal sphincter injuries (OASIS) using first a cross-sectional and then a matched pair analysis. Design A matched cohort. Setting Data was gathered from the Finnish Medical Birth Register from 2004–2011. Population All singleton vaginal births (n = 303,758). Methods Women resulting matched pairs (n = 63,925) were matched based on baseline risk of OASIS defined based on parity (first or second/subsequent vaginal births), age, birth weight, mode of delivery, prior caesarean section, and length of active second stage of birth. Results In cross-sectional analysis episiotomy was associated with a 12% lower incidence of OASIS (adjusted odds ratio (aOR) 0.88, 95% confidence interval (CI) 0.80 to 0.98) in first vaginal births and with a 132% increased incidence of OASIS in second or subsequent vaginal births (aOR 2.32, 95% CI 1.77 to 3.03). In matched pair analysis episiotomy was associated with a 23% (aOR 0.77, 95% CI 0.69 to 0.86) lower incidence of OASIS in first vaginal births and a 61% (aOR 1.61, 95% CI 1.14 to 2.29) increased incidence of OASIS in second or subsequent vaginal births compared to women who gave birth without an episiotomy. The matched pair analysis showed a 12.5% and a 31.6% reduction in aORs of OASIS associated with episiotomy, respectively. Conclusions A matched pair analysis showed a substantial reduction in the aORs of OASIS with episiotomy, due to confounding by indication. This indicates that results of observational studies evaluating an association between episiotomy and OASIS should be interpreted with caution.

Inflammatory response to surgical trauma in patients with minilaparotomy cholecystectomy versus laparoscopic cholecystectomy: a randomised multicentre study

ABSTRACT Objective The aim of the study was to evaluate the inflammatory response to surgical trauma in minilaparotomy cholecystectomy (MC) compared to laparoscopic cholecystectomy (LC). Assessment of inflammatory response to surgical trauma in MC has not been addressed properly. Therefore, we investigated five interleukins (IL) and C-reactive protein (CRP) in MC versus LC group in a prospective randomised trial. Methods Initially, 106 patients with non-complicated symptomatic gallstone disease were randomised into MC (n = 56) or LC (n = 50) groups. Plasma levels of five interleukins (IL-1β, IL-1ra, IL-6, IL-8, IL-10) and hs-CRP were measured at three time points; before operation (PRE), immediately after operation (POP1) and six hours after operation (POP2). The primary end-point of the study was to compare the plasma levels of five interleukins and CRP in LC versus MC group. Results The demographic variables and the surgical data were similar in the study groups. The patients in the MC group had higher elevation of the CRP mean values post-operatively (p = 0.01). However, the patients in the MC group had higher elevation of the IL-1ra mean values post-operatively, the mean pre-/post-operative IL-1ra values being 299/614 pg/ml in the MC group versus 379/439 pg/ml in the LC group (p = 0.003). There was no statistical significance in IL-6 mean values between the MC and LC groups pre- and post-operatively (POP1). However, the patients in the MC group had higher IL-6 mean values six hours post-operatively (POP2), the mean IL-6 values being 27.6 pg/ml in the MC group versus 14.8 pg/ml in the LC group (p = 0.037). In addition, the patients in the MC group had higher elevation of the IL-6 mean values post-operatively, the mean pre-/post-operative IL-6 values being 4.1/27.6 pg/ml in the MC group versus 3.8/14.8 pg/ml in the LC group (p = 0.04). There was no statistical significance in IL-8, IL-10, and IL-1β mean values between the MC and LC groups pre- and post-operatively. Conclusion Our results suggest that the inflammatory response in MC versus LC groups was similar based on the IL-8, IL-10, and IL-1β values. A new finding with possible clinical relevance in the present work is higher relative elevation of the IL-1ra and IL-6 mean values post-operatively in the MC group.

Cholecystectomy Patients with High Plasma Level of Catalase Have Significantly Lower Analgesia Requirement: A Prospective Study of Two Different Cholecystectomy Techniques with Special Reference to Patients with Cancer

Background/Aim: The plasma level of the oxidative stress biomarker catalase in patients with gallstone disease has not been previously compared with that of patients with cancer. Moreover, the number of analgesic doses required during the first 24 h postoperatively (NAD24) after laparoscopic cholecystectomy (LC) or mini-cholecystectomy (MC) in patients with gallstones is unreported. The aim of the present study was to determine the correlation between the plasma catalase level in patients with gallstones according to cholecystectomy technique versus patients with cancer. Patients and Methods: Initially, 114 patients with symptomatic gallstone disease were randomized into LC (n=54) or MC (n=60) groups. The plasma level of catalase was measured immediately before, immediately after and 6 hours after operation. Results: The median plasma catalase levels preoperatively and following surgery in the LC and MC patients versus those with cancer did not differ statistically significantly. The median plasma level of catalase increased immediately after operation, but the alteration was statistically insignificant (p=0.132). Interestingly, there was a statistically significant weak inverse correlation between the individual NAD24 and median plasma catalase values postoperatively in patients with gallstone disease (r=−0.283, p=0.042). Conclusion: The plasma catalase levels preoperatively and following surgery in the LC and MC patients versus those with cancer were quite similar. Cholecystectomy patients with high plasma levels of catalase appeared to require significantly fewer analgesic doses during the first 24 hours postoperatively (NAD24), suggesting that better oxidative balance following surgery could have a protective role against postoperative pain.

Gallstone Patients with Enhanced Oxidative Stress Biomarker Superoxide Dismutase (SOD1) Plasma Levels Have Significantly Lower Number of Postoperative Analgesic Oxycodone Doses: A Prospective Study with Special Reference to Cancer Patients

Background/Aim: Oxidative stress biomarker superoxide dismutase (SOD1) plasma levels in operated gallstone patients versus cancer patients are unknown. In addition, the number of analgesic doses during the first 24 h postoperatively (NAD24) in gallstone patients operated with laparoscopic cholecystectomy (LC) or minicholecystectomy (MC) is unreported. The aim of the study was to determine a correlation between the plasma SOD1 levels in the LC and MC patients versus cancer patients. Patients and Methods: Initially, 114 patients with symptomatic gallstone disease were randomized into LC (n=54) or MC (n=60) groups. The plasma levels of the SOD1 marker were measured just before, immediately after (POP1) and 6 h after the operation (POP2). Results: The median plasma SOD1 levels preoperatively and following surgery in the LC and MC patients versus cancer patients were statistically insignificant (p=0.90, p=0.88, p=0.21, respectively). The median plasma levels of SOD1 increased immediately after operation (POP1) and the postoperative elevation between the preoperative (PRE) and the POP1 values in the SOD1 marker were statistically significant (p=0.027). Then the median plasma levels of SOD1 marker decreased 6 h postoperatively (POP2) and the decrease between the POP1 and POP2 values in the SOD1 marker were statistically highly significant (p<0.001). There is a highly significant inverse correlation between the individual values of the NAD24 and plasma SOD1 values postoperatively in LC and MC patients (r=−0.335, p=0.011). Conclusion: The plasma SOD1 levels preoperatively and following surgery in the LC and MC patients versus cancer patients were quite similar. Cholecystectomy patients with enhanced levels of SOD1 appeared to have significantly lower number of analgesic oxycodone doses during the first 24 h postoperatively (NAD24).
